Patented Aug. 2, 1938 HEEL-ATTACHING MACHINE Robert H. Lawson, Beverly, Mass., assignor to United Shoe Machinery Corporation, Paterson, N. J., a corporation of New Jersey Application December 8, 1936, Serial No. 114,827

31 Claims.

My invention relates tothe attachment oi heels or heel-portions to shoes and is particularly directed to machines of the character of that disclosed in Letters Patent of the United States No. 2,033,248, Lawson, `March 10, 1936. The apparatus of the above-identified patent is especially designed for operation upon a type of shoe provided in its heel-seat and in a heelbase and lift to be attached with locating openingsprojections from the top of a jack upon which the work is held for the operations upon it, are arranged in the correct relation for attachment. To ordinary commercial Work, however, from which these openings are absent, the machine of the patent is not directly applicable, and an object of my invention is to provide for the operation of such a machine upon shoes which 20 are without special locating means. In the attainment of this object, I utilize a heel or heelportion to be attached as the means for effecting the location of the Work, there being means movable into contact with it to control registration between the heel and the shoe to which it is to be attached, the two being supported upon holders which are movable relatively. The controlling means having been positioned by the heel, it may be locked and then will not only be accurately effective in connection with an operating mechanism for which it is thus set, but also for other operating mechanisms. Consequently, after the controlling means has been adjusted, it will serve to produce the registra- 35 tion of the shoe with successively operating mechanisms, as in a turretmachine, such as the previously mentioned patent illustrates. At the termination of the operating cycle of the ina-- chine, the lock is released, so the controlling 40 means may be set-for the next heel and shoe operated upon. The operating mechanism which holds the heel for the initial performance of its locating function preferably has an abutmentsurface for contact with the heel and a breastgage extending from said surface. About the abutment member may move operating sections for pricking the work or inserting fastenings in it, there being connections between opposite sections for compelling them to move uniformly in opposite directions. This, with the manner in which the shoe-holder is moved into operating position, insures the correct transverse relation between the heel and heel-seat. With the rear of the heel, a controlling member is arranged to contact, and by this the position of the shoe- These openings when alinedwith one another by.Y

holder is governed to cause registration between the heel and the heel-seat longitudinally of the shoe. To facilitate the introduction of the heel between the sections and the controlling member, means is preferably provided for moving them away from the abutment member. The position-controlling means which I have chosen to illustrate includes the controlling member just mentioned, which may be in the form of an arm pivoted upon the operating mechanism, and a slide movable by the arm and having a guideslot. In this slot, a projection from the shoeholder, mounted to slide upon a carrier which shifts the holder into and out of co-operation with the operating mechanism, may be directed after the controlling slide has been locked in the position determined by the heel. As clamping pressure is applied to the work, this slot determines the registration between the heel and the heel-seat, and by maintaining the lock until the end of the operating cycle, a like effect may be obtained for successively acting operating mechanisms. The application of the locking means may be initiated by a member movable with the shoe-holder when the machine is started, so the positioning means is made ready for action before power-operation begins.

In construing the claims of this case, it is to be understood that the term heel, which has been employed for the sake of conciseness, applies equally to a whole heel or to a heel-portion, as a base or a top-lift of rubber or other material.

In the accompanying drawings, illustrating a particular form of the invention,

Generally, the apparatus has the form of that disclosed in Patent No. 2,033,248. Upon a frame l0 a turret I2 is rotated during each cycle of the machine in three steps, to present at an operating position mechanisms for pricking and preliminarily nailing a heel-base to a shoe, for driving the attaching nails into the pricked openings and for nailing to the base a rubber` or other lift. For each step, the turret is stopped, the operation performed by one of the three mechanisms which it carries, and then said turret is turned through 120 to present the next mechanism at the operating'position. One of the lmechanisms, designatedas A, is shown in some detail in the drawings, this being for the pricking and preliminary nailing. Another of the mechanisms is indicated as B, this being for nailing the lift, which is automatically presented for attachment by a holder b. A lasted shoe to be heeled is supported upon a holder D, of which there may be two, as in the patent, although only one is herein illustrated. The holder may be as in Letters Patent of the United States No. 1,932,551, Lawson, October 31, 1933.

projection' 2l dependingfrom it, in horizoi'italv ways 25 formed in a member 28. 'I'his member is vertically reciprocableupon the lend of an arm 3l) pivoted at one side ofthe machine to occupy,V

alternately, positions in'which theshoe is introduced into the holder D and in which it is: presented to the mechanism A and the *associated* mechanisms. In the latter relation, to which it is swung initially by the operator, it contacts with a lever 32 and through a horizontally re-,f

ciprocatory rod 34 and 'lever r36 trips a* clutch mechanism 38 to starty thepower-operation ofthe apparatus. In the operating position, the carrier 28 for the holder-plate M is alcovel a member 45 vof mechanism by which'preliminary and nai pressure are applied to the shoe in the holder to clamp it forthe operations to be performed;

The turret l2 has a horizontal, circular plate 42 from which depends an abutment-post M of the operating mechanism A, and against which the pressure mechanism forces the work. In vertical passages in the abutment reciprocate drivers 46, 46 secured to a plunger 58, which,y when' the mechanism A is in active position, will be under the influence of an actuating lever 5i] oscillated under the power of the machine. kT'hese drivers insert through a heel-base applied `to the heel-seat of a` shoe in the'h'older D, two nails supplied to the driver-passages through tubes 52. The base is thus secured for the succeeding operations. Pivoted at their upper extremities upon the plate 42 are six. operating .sections of., the mechanism A, consistingV ofla' forward' side pair 54, 55, a rear side pair 55, 56 andia'rear pair 58. In each'of the sections 54, 54'are two vertical passages, while the other sections each contains one passage. VIn each passagean awl @t is arranged to reciprocate, it being joined4 to the plunger 138 by a link e2. These awls prick in the heel-base openingsfor the reception -of, six attaching nails. rihe sections arerurged inwardly by spring-actuatedy plungers Gil movable upon a plate 65 ci the turret I2 and are lockedin their orward positions during the pricking operation by l*wedge members 6B actuated by the piunger 46.

Of this, it is only.M necessary to say that a plate` lll has rising fromA The piate lil isgmov- The more important features of the present invention will now be considered. The abutmentpost 4d has at its forward edge two downward projections or gages 68 provided with substantially vertical, inner contact-faces. Against these faces a heel-base is to be placed with its.

tread-surface up. Each of the pricking sections is provided with a depending l,gage-portion lll arthe base is to venter when applied to the postv 44. l and its projections, means is furnished whereby `the operator mayy simultaneously swing out the sections of the post. Movable in a horizontal passage in.V the post isaJ plunger 'l2 contacting at its inner extremity with one of ythe sections, there being a plunger for each section; In vertical passages in the post reciprocatetwo primary plungers 'ld and'lS. `Upon the plunger lare two annular, downwardly and inwardly inclined surfaces 'i8 and Si] arranged to engage the inner extremities of the secondary plungers of the sections 55 and 58, respectivelyE Asimilar surface 82 upon the primary lplunger l5 contacts` with the secondary plungers ofthe sections 5G.-

A horizontal pinll connects thev plungers v'lll and I6, compelling them; to move together. v AjspringA 85 maintains them normally elevate'd. From' opposite-sides of the plunger l'M are projections 85,

86, which are received by theiforked inner ,ends l a lever 88 fulcrumed upon the post *Asv the turretl2 rotates, and thenmechanisrn A reaches the operating position, aroll 55 upon the outer end of thislever enters the vforked extremity of-a hand-lever 92 v'fulcrurned,upon the frame i5. The hand-lever is normally held with its fork properly alined with the path of the roll Se by an adjustable stop 94 against Awhich a shoulder upon the lever is forced by a torsion-spring 9G. When the operatory depresses the hand-lever, and the inclined surfaces of the primary plungers lf3 and 15 are forced by the lever 8S downwardly, their inclined surfaces "i8, 85 and 8E actupon the secondary plungers to press these against the operating sections and swing them outwardly. This movement is sufficient-to remove the'gagle-portions Il) of all the operating sections 4from the area at the end of the post which the largest heel-base will occupy. Upon release of the handlever, the springs 85 and 95 :will restore the plungers and their actuating means to their initial positions, and the spring-plungers 55 will carry the gage-portions 'le of the sections into contact with the heel-base which has been applied to the end of the post mand definitely located fore and aft of the machine by the projections 68. To obtain a corresponding lateral positioning the to be compelled to move equallyand oppositely with respect to avertical plane through the center` of the lpost andthroughthe longitudinal axis of` the shoein tlie'h'ciderl D. To this end, an equal-armed lever Vlil@ -isfulcrumed upon the front the pest and is joined at its'ends by links |52, H12 to the respective sections 55, 54. Therefore, as the plungers 55 carry these sections in, the heel-base is symmetrically located laterally of the heel-seat. At the same time, the awls 50 are correctly spaced from the periphery of the base by the contact of the gage-'portion 'm with said periphery, and the awls of the sections 56 base, the pricking` sections 54 are so joined as and 58 are similarly positioned, ready for the pricking operation. Y

' The lateral relation of the lshoe in the holder is established by the guidance of the holderplate I4 in the ways 26 inV a direction parallel to the longitudinal axis of the tread-surface of the heel-base, held as just described, and by the symmetrical action of the holder-arms 20 and 22, as set forth in the previously-mentioned Patent No. 1,932,551. There remains'the proper longitudinal presentation of the shoe in the holder to the heel-base at the operating positionv A and the maintenance of this relation for the other operating positions. For this purpose, I employ the base itself as a cage. Fulcrumed upon the under side of the turret-plate 42 Iat the rear of the post 44 is a controlling lever ||0, the main arm of which extends downwardly to a point at the back of the heel-base and in its horizontal plane; Ashort arm I I2 projects forwardly beneath a horizontal pin ||4 xed in the primary plunger '|4. By this connection, the movement of the hand-lever 92 is communicated to the controlling lever IIU. Against the rear of the lower end of the lever I I0 bears the horizontal extension I I6 of an arm I I8 rising from a holderlocating slide` |20 guided to reciprocate horizontally in the frame I0 below the turret I2. Into engagement with the leverv the arm-extension is urged by an expansion-spring |22 interposed between it and the frame. By this engagement, the slide is positioned with respect to the rear of the heel-base. The forward end I 24 of the slide isenlarged to permit the formation in it of a vertical recess or vslot |26'into which ts transversely a roll |28 rotatable upon one side of the plate |4 of the holder D. The roll is mounted in a predetermined relation to the back-stop I8, by which the shoe is located longitudinally of the holder. The bottom of the slot expands, fore and aft of the machine, to furnish a throat, the sidewalls I30, |30 of which will receive contact of the roll |28 to direct it into the body |26 of the slot. The slide |20, |24 will have been positioned by the heel-base and the lever I0 to correctly locate the'holder D and the heel-seat of the shoe therein when the roll |28 is received by the slot |26.

Before this action upon the holder D occurs, the slide |20 must be secured in the place to which it has been adjusted; Above the slide, where it passes through the frame I0, two locking cams -|32, |32 are rotatably mounted, these having oppositely acting eccentric surfaces |34, |34 which are normally forced intoV engagement with the f upper edge of the slide by a spring ,|36 joining arms |38, |38 depending from the shafts of the cams. As the holder D isswung into the operating position beneath the mechanism A, and the lever 32 moved by contact of the arm 30 shifts the rod 34 totrip the clutch 38, one of a pair of collars |40, |40 upon the rod contacts with a bell-` crank-lever |42 fulcrumed upon the frame. To the forward extremity of a substantially horizontal arm of the bell-crank,Y a vertical bar |44 is articulated, this being guided to'move adjacent to Y overlapping arms |43, |46 fast from the shafts of the position to which it has' been adjusted by the lever I I0.V Upon the starting of the power-operation of the machine and the application of pressure to the work by the rising of the member 40,- the roll |28 will be located somewhere beneath the outer extremities of the inclined walls |30, |30V and will enter the slot |26, either directly or being cammed toward it by one of the walls. When the roll is in the slot-portion |20 of the locked slide |20, the shoe will have been fixed in the correct longitudinal relation to the heel-base in the mechanism'A. The lateral relation has been determined by the arms 20 and 22, together with the definite location of the ways of the plate I4, and the work is ready for the operation upon it. After this has been performed, the holder D is lowered by the member 28 to allow the turret I2 to bring the succeeding operating mechanism above the; holder D. Because, throughout the operating cycle, the rod 34 remains in its forward position, the lock is maintained upon the slide |20. Therefore, as each of the other operating mechanisms, as that for base-nailing or lift-nailing, arrives at the holder D, and the member 28 rises to apply pressure to the work, the entrance of the holder-roll |28 into the slot |26 will, as before, produce the desired relation between the heelbase, which is now upon the shoe, and either the base-nailing mechanism or the lift-nailing mechanism. At both mechanisms, a condition of approximate registration with the operating sections is produced, these being more exactly posititoned, as in Patent No. 2,033,248, by the contact of their gage-portions with the attached base upon the shoe. At the lift-nailing mechanism B, the breast of the attached'base .is correctly located for alinement with it of the breast of a lift automatically presented by the holder b.

Considering the action of the apparatus, with the carrier-arm 30 drawn out from the operating position, the operator places a lasted shoe S in the holder D and clamps it in place by shifting the lever 24. He also supplies a heel-lift 7L to the holder b and applies a heel-base H against the gage-projections 68, 68 upon the lower extremity of the post 44 of the preliminary nailing and pricking mechanism A, which is in operating position. For the last-mentioned purpose, the operating sections and the arm H3 will have been carried away from the post by the lever 92, release of which will allow the sections to clamp the base in place and laterally locate or centralize it by the connected sections 54, 54. The arm 30 is swung in to operating position, and as the heel-seat of the shoe S in the holder D moves across the heel-base, it is presented in the proper lateral relation thereto because of the manner in which the elements of the machine are supported and moved, the longitudinal axis of the heel-seat'coinciding with the corresponding axis of the heel-base in the holder. As to the relation of the heel and heel-seat along the common longitudinal axis, the primary controlling member or arm |I|l will have been located in accordance with the length of the base, and the normally unlocked secondary controlling member or slide |20 will be correspondingly positioned by engagement of the arm-extension ||6. When'the arm 30 reaches the point at which it acts upon the lever 32 to start the machine in operation, the bar |44, governed by the starting rod 34, releases the cam members |32, |32 to lock the controlling slide as it has been Set by the heel-base. Under the powerof the machine, the member 28 rises through the arm 30 to clamp the work, and the entrance ofthe holder-roll |28 into the guideslot |26 of the controlling slide shifts the holder D longitudinally of the heel tol bring thebreastline of the sole into registration with the breast of the heel. These elements will therefore be properly related for their preliminary attachment and pricking regardless of the size of the shoe. Since the rod 34 remains in the rearward clutch-controlling position throughout a rcomplete rotation of the turret l2, the lock is retained bythe cams |32 upon the controlling slide for a like period, and upon velevation of the Y holder D in the presentation to it of the succeeding operating mechanisms, its roll 28 will cause the regis-tration of the heel-base attachedV to the shoe S in the holder with such operating mechanisms and with the lift h in the holder b. At the completion of the operating cycle, the outward movement of the arm 30 releases the rod 34.

` This lowers the bar E44 to unlock the slideY l2,

preparing the machine for the succeeding operation. 7
